The effect of higher versus lower wattage e‐cigarettes on smoking: A randomized controlled trial

Addiction, EarlyView.
Abstract Aims To assess whether higher wattage e‐cigarettes (HWe), with improved nicotine delivery, enhance complete substitution compared with lower wattage e‐cigarettes (LWe) and whether complete switching lowers exposure to a cigarette‐derived lung carcinogen, using urinary 4‐(methylnitrosamino)‐1‐(3‐pyridyl)‐1‐butanol (NNAL) as a biomarker.
